In the case of the heteropolymer poly(D,L-lactide) (PDLLA), it has been shown that the crystallinity degree (17) and the crystallization rate (18) decrease with the increase in D-lactic acid content in PLA (10).
Xu's lab then created random heteropolymers, which they call RHPs.
Lignocellulosic biomass is composed mainly of cellulose ([beta] (1-4)-linked chains of glucose molecules), hemicellulose (heteropolymers composed of 5- and 6-carbon sugars such as arabinoxylan, xylan, glucronoxylan, glucomannan, and xyloglucan) and lignin (polymer of three phenylpropanoid units: p-hydroxyphenyl, guaiacyl, and syringyl).

Polyacrylamide (PAAm) and their heteropolymers are of great importance, because of their good thickening capability, flocculation, and rheological behavior [1], Polymers based on acrylamide (AAm) and their derivatives are easily available and relatively economic; moreover, these water-soluble materials offer a unique combination of useful properties [2-5].
Cellulose is a polymer of glucose, accounting for 30-50 wt% of dry LCBM; hemicellulose is a mixture of heteropolymers containing various polysaccharides, such as xylan, glucuronoxylan, and glucomannan, accounting for 20-35 wt%; the mainly remaining portion with 15-30 wt% is lignin, which is a multisubstituted phenolic polymer.
